I'm a native Baltimore girl, so when I say crab shack, I mean caught in the Bay, piles of shells on the table, plastic bibs and cheap beer... But most importantly, Bay crabs - not Gulf crabs. There are tons of tourist places around, and it's really hard to identify from the mainstream tourist sites what's going to be good.
I trust Chowhounders - but I couldn't find a post newer than 3 years ago, so hopefully someone's been over the Shore this summer and had a good experience!? Thanks guys!
